Key Terms, Fundamentals Ch. 17 Vitals
| Term | Definition |
|---|---|
| Afebrile | without fever |
| ausculatory gap | period of sudden silence between first Korotkoff sound heard (systolic bp) and next Korotkoff sound heard when it resumes at a number 30-40 mmHg lower in some hypertensive patients |
| Biot's respirations | respirations characterized by groups of several shallow breaths followed by variable-length periods of apnea |
| Bradycardia | pulse below 60 bpm |
| Bradypnea | respiratoratory rate below 12 respirations per minute |
| Cheyne-Stokes respirations | pattern of respirations starting shallow, gradually increasing in depth and frequency to a peak, then decrease in depth and frequency until they are slow and shallow, then a period of apnea lasting from 10-60 seconds |
| diastole | time when ventricles are at rest |
| diastolic pressure | measurement of the pressure exerted by the blood on the artery walls while the ventricles are not contracting, which is the lower of the two pressures |
| dyspnea | labored or difficult breathing |
| eupnea | respirations in which the rate, depth, rhythm, pattern, and respiratory effort fall within normal parameters |
| febrile | state of having a fever |
| hypertension | high blood pressure - systolic above 140 or a diastolic reading consistantly over 90 |
| hypertension, primary | "essential hypertension" rise in blood presure that occurs as a result of the heart's having to work harder to pump blood through artery walls made less elastic due to arteriosclerosis |
| hypertension, secondary | blood pressure that becomes elevated due to renal or endocrine disease |
| hypotension | low blood pressure, blood pressure that suddenly falls 20-30 mmHg below an individual's normal blood pressure or one that falls below the low normal of 90/60 mm Hg |
| hypothermia | individual's core temperature below 95 degrees F (35C) |
| orthopnea | individual finds it too hard to breathe unless positioned in an upright position such as sitting or standing |
| pulse deficit | state when radial pulse is slower than apical pulse |
| pulse pressure | measurement of difference between systolic and diastolic pressures - found by subtracting diastolic from systolic. Normal range is 30-50 mm Hg |
| sphygmomanometer | aneroid or electronic pressure manometer (gauge) that's used to measure blood pressure |
| stridor | audible, high-pitched crowing sound that results from partial obstruction of the airways |
| systolic pressure | measurement of the force exerted by the blood against the walls of arteries during contraction of the heart ventricles, which is when the pressure is highest |
| tachycardia | pulse greater than 100 beats per minute |
| tachypnea | respiratory rate that exceeds 20 respirations per minute |
